Notes: Total Surface Water Impacts (include removal of existing piles and proposed piles) = 46.6 sq ft.
Temporary Impacts result from removal of existing piles and Permanent Impacts result from installation of proposed piles.
33 exitsing piles at 0.8 sq ft per pile = 26.4 sq ft.
14 proposed piles at 1.4 sq ft per pile = 20.2 sq ft.
